Brainly says you need the following points
- The pattern is min-zero-max-zero-min, which is the pattern for a cosine function of the form y = acos(x) + k, but is reflected over the x-axis (so a < 0).
- The amplitude is |a|, so a = –1 and |a| = 1.
- The midline is exactly between the max and the min, y = (6 + 8)/2 = 7, so k = 7.
- The equation is y = –cos(x) + 7.
Answer:
The circumference of the clock is 
Step-by-step explanation:
we know that
The circumference of a circle (clock) is equal to

In this problem
The long of the minute hand is the radius of the circle
so

substitute
-----> exact value of the circumference
Y intersect is the answer
<span>The formula is area of trapezoid = average base x average height
We're going to do this in reverse.
Area = 80.75
[(7 + 12)/2] = 9.5 (height)
height = 80.75 / 9.5 = 8.5
The height is 8.5, so the answer is D.</span>
Let's call the length of the rectangular fence
and the width of the rectangular fence
.
Based on the information in the problem, we can make two equations, based on the formulas for perimeter and area:


Now, let's substitute in the values we are given in the problem:


Now, let's solve the system using substitution.

- Solve for
from the first equation

- Substitute this value into the second equation


- Multiply both sides of the equation by


- Subtract
from both sides of the equation

and 
- Use the Zero Product Property and solve both factors


We are given two possible lengths. However, the funny thing is that both produce the same dimensions: 24 ft by 10 ft:


Thus, our answer is Choice C, or 10 feet by 24 feet.
